About Ferri-taramiteHide

Formula:
Na(CaNa)(Mg3Fe3+2)(Al2Si6O22)(OH)2
The taramite group minerals are sodium-calcium amphiboles defined with A(Na+K+2Ca) > 0.5 apfu and 1.5 apfu < C(Al+Fe3++2Ti).

Ferri-taramite is defined with

A position: Na dominant
C2+ position: Mg dominant
C3+ position: Fe dominant
W position: (OH) dominant
Colour:
Dark brownish black (greenish yellow to brown in splinters)
Lustre:
Vitreous
Hardness:
6
Specific Gravity:
3.227 (Calculated)
Crystal System:
Monoclinic
Name:
Named according to the amphibole nomenclature in force (Hawthorne et al.,2012). The root name, taramite, is for the taramite group type locality, Walitarama, Mariupol, Ukraine.

Taramite was originally defined with Fe2+>Mg in the C2+ position, but this was changed in the 2012 amphibole nomenclature. The mineral defined as Ferri-taramite in this nomenclature was named ferri-magnesiotaramite pre-2012.
An amphibole of the sodium–calcium subgroup of the amphibole supergroup.
The CFe3+ analogue of taramite.

The taramite group is in the 2012 nomenclature defined with C(Al+Fe3++2Ti) > 1.5 apfu, whereas the pre-2012 definition used the T position, i.e 5.5 < Si < 6.5 apfu. This redefinition does not change the formula, but some amphiboles qualifying as taramite pre-2012 will now be ferri-katophorite. Since the content of the C3+ position was not part of the pre-2012 definition, it was often omitted in the presentation of data.

Optical Data of Ferri-taramiteHide

Type:
Biaxial (-)
RI values:
nα = 1.670(5) nβ = 1.680(5) nγ = 1.685(5)
2V:
Measured: 70° (10), Calculated: 70.2°
Max. Birefringence:
δ = 0.015
Based on recorded range of RI values above.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.

Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.

Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

Surface Relief:
Very High (positive)
Relative to Canada balsam mounting medium (n ≈ 1.537).

This shows the grain boundary and Becke line effect under plane-polarised light, based on the contrast between this mineral's average refractive index and the mounting medium. It does not take into account mineral colouration.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure - the conoscopic view for a grain cut perpendicular to the acute bisectrix, using this mineral's 2V. The two small white dots mark the melatopes - the points where the two optic axes emerge - and are shown only when they fall within the field of view. The coloured bands are isochromatics, and the dark bands are isogyres.

Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
Pleochroism:
Strong
Comments:
Strong in transmitted light, with X pale yellow, Y dark brown, Z yellowish brown and absorption Y>Z>X.
